(a) The acceleration of the salt shaker is 1.18 m/s².
(b) The distance traveled by the baseball player before coming to rest is 204.1 m.
<h3>
Acceleration of the salt shaker</h3>
The acceleration of the salt shaker at the given coefficient of kinetic friction is determined as follows;
a = μg
a = 0.12 x 9.8
a = 1.18 m/s²
Acceleration of the baseball player is calculated as follows;
a = μg
a = 0.4 x 9.8
a = 3.92 m/s²
<h3>Distance traveled by the baseball player</h3>
The distance traveled by the baseball player before coming to rest is calculated as follows;
v² = u² - 2as
0 = 40² - 2(3.92)s
0 = 1600 - 7.84s
7.84s = 1600
s = 204.1 m
The complete question is below:
A baseball player slides into third base with an initial speed of 40 m/s. If the coefficient of kinetic friction between the player and the ground is 0.40, how far does the player slide before coming to rest?
